That’s interesting. I tried adjusting both the latch and striker and neither had slots, only round holes. So, I as previously posted I simply milled a couple of slots.
Yes, I had access to a milling machine. However, a Dremel with a metal burr bit would do the job as well. I didn’t to remove much material about 1/4”. As a last resort you can simply file the slots. This would take a bit more time but is easily done.
I had a similar situation. Unfortunately, for reasons unknown to me, Tesla did not provide a means of adjusting the tailgate strikers. My tailgate was out quite a bit so I removed the strikers and had horizontal slots milled into them which allows the strikers to be moved forward. Worked...
